Incertain cases it is necessary to subject; theseparatingliquids or the fibrous :matter or foreignmatter to preliminary treatnumt in order to render them capable of treatment bythe apparatus. It has for exz1mple-liee11 found that certain pigments f'cannot, owing to their chemical composidtion,be separated from the fibers by ,the

apparatus without preliminary treatment, this applying particularly to mineral pigfwments. The particular mode and sequence i of operatioi'isdepend on the particular rerating quirenientsineaeh case; for instance, the f which fibrous matter may beg'round or notground beforewbeing subjected to the preliminary treatment or the separating treatn'ient.

The following isan example of the use of the apparatus in connection with Waste 7 paper, for the purpose of eliminating printin tfink, size and the like, and enabling the eefialose to be usedfor the manufacture of pazperagain: In the first instance the waste "paperiis boiled under pressure in a dilute a solution of sulfite,"as forginstance sulfite of soda, so that thewoody matter is converted fintowcellulose and able-aching effect is projduced, the effect ofboiling underI pressure it being to accelerate the function of the ajppa- 8O Y'atus and enable higher temperature to be employed without fear of the matter being disintegrated beyond the desired point by the development of steam bubbles which would render the subsequent washing more difiicult; Themass isthen washed until it gives 1 a neutral reaction and is ground, whereupon water ,isadded thereto until a a thin pulp u with a low concentration offibers' "is'fproduced. This latter dilution may also be efl'ected with a weakly acid liquor, This. lii 'hlv diluted pulp is then passed through pipekhl shown in the accompanying diaiviiigs into the apparatusA, while a suitable oil such as benizin is fed to the appe'fratus through a pipe N. "e g t H 1 The apparatus used comprises a plurality rout of emulsifying appliances A.. A, etc, and

t separators l B ,etc,, alternating w 1th each I bther and arrai'iged in series, so that the t liquid containing the fibrous'matter passes immiscible, from: the first separator to the second emulsi- Q fying appliance, thence to the second sepahY a tQr and through the same. to tllQtllUCl {emulsifying} apparatus and so 'forthfi un'ti'l the desi fed e flfectii's obtained, 1 Each emulsia Iying'epparatus comprises a casing in the interior of which? are mounted on a rotary 1 betweenWwhieh- "are disposed stationary dished platesflor funnels. c.
